UNITED s'rArss PATENT 'OFFICEL FLOAT.

Application filed March 14, 1927. Serial No. 175,213.

The presentinvention relates to a float, and has for its prime object to provide a foldable4 structure, which may be readily carried about when not yin use, and which .may be readily and easily unfolded to an extended position for use in the water.

Another important object of the invention lies in the provision of afloat of this nature, which has means associated therewith wherebyit may be propelled and steered when in the water. i i n A still further important objectof the invention lies in the provision of a collapsible and foldable float of this nature which is exceedingly simple in its construction, inexpensive to manufacture, compact and convenient, thoroughly reliable and efficient, and otherwise Well adapted for t-he purpose for which it is designed.

With the above and numerous other objects in view, as will appear as thedescription proceeds, the invention resides in certain novel `features of construction and in the combination and Varrangement of parts as will be hereinafter more fully described and claimed. v

In the draw-ing, Figure 1 is a. side elevation of the float showing the same extended.

Figure 11 is a detail perspective showing a portion of the actuating lever.

Figure 12 is a detail section, taken through one of thev pneumatic floats.

Figure 13 is a sectional view through one of the pneumatic fioats, and

Figure 14 is a sectional view through the Acentral panel, showing the manner in which the steering lever and seat are mounted.

Referring to the drawing in detail, it will be seen that the numeral 5 denotes a central panel. preferably of square formation, havmg hinged to each edge a rectangular panel 6, by means of hinges 7. Two of the op-,

posed side panels 6 have square panels 8 and 9 hinged thereto respectively, as at 10 and 11. The hinge 10 is located so thatthe pintles are spaced from the edge of the side 6 adjacent the panel 8, so that-the panel 8.

may be folded under the panel 9, as is iny dicated to advantage in Figures 5 and 6. On the'ends of the other two panels 6 there are mounted inflatable pneumatic floats 14, preferably of spherical formation when inflated, having straps 15 on the'sides thereof, with which are engaged cables 16 or the like,

which are engaged with the panels as at 17. vThere are preferably four of the straps 15 and the cable 16 for each float 14. Similar floats 14 are mounted on panels 8 and .9, by similar means 15 and 16. panels are inthe extended position shown in Figures 1 and 2, it will be seen that these floats will support the structure in the water.

1t will also be apparent that the floats 14 and 14 may be deflated and that the panels may be folded as indicated in Figure 6 and then to the fully closedpositionas shown in Figures 4 and 5.

When the Y A rudder 18 is carried by a curved bar ,i

19, fixed to a bar 20, which is-pivoted in#y termediate its ends as .at 21 adjacent the router edge of the panel 8. A ring 22 is rotatable in the center of the panel 5 about an openingl 23 andI has arms 24 extending downwardly therefrom through the openings 23 and these arms vsupport a bar 25. Cross cables 26 connect the ends of the bars 20 and 25. Legs 28 extend through the opening 23 and have a seat 29 mounted on their upper ends.A The legs 28 straddle the vcenter of the bar 25 and move in notches Thus it will be seen that by turning the seats 29 through thek legs28, bar. 25,v vcross cable 26 and bar 20, the bar 19 may A be swung toy move the rudder 18 for steering purposes. A; pin 30 is inse-rtablein openings 31 in the legs 28, sol that they may n be held in a raised position, shown in Figure 1. Vhen the s tructureis toT be folded this pin is removed and the seat moves downwardly toi-est on the panel 5.

'Brackets 33 are mounted on the/ panel 6 to which the panel 9 is hinged. A propeller frame F is pivoted in the brackets 33.

This frame structure is shown to advantage in Figures 8 and 9 and includes a main bar 35 mounted on a pair of angle members 36 at one end and angle members '37 at the other end. Rods 38 extend between these angle members. Straight cross members 39 are mounted on the bar 35 and Vshaped member 4() are mounted thereon. Blades 41 are hinged on the rods 38 and are limited in their movement between the V-shaped members 40 and the straight members 39. The angle members 36 are pivoted, as at 42, in the brackets 33, and are connected to a link 43. This link 43 is connected to arms 44 as at 45. A pin 46 -extends between intermediate portions of the arms 45. These arms45 are hinged below an opening or slot 47 in the panel 6 on which the brackets 33 are mounted. This pivotal mounting is afforded by a'pin 48 carried in brackets 49. An actuating lever 50 has a slotted end which straddles pins 48 and 46 and has an extension 52 hinged thereto as at 53, which may be heldin an extended position by means of a removable pin 54.

On the panel 5 there is mounted a socket 56 for receiving an umbrella or the like. Also on the panel 5 there is mounted a handle 57 for carrying the structure. about.

From the above detailed description itwill be seen that we have devised a float structure which is simple in its construction and when extended will support the weight of a person sitting on the seat who may propel the float by the lever 50 and its extension 52. The float may be steered by turning the seat as explained. Now, when the float is not in use, the floats of a pneumatic type shown at 14 and 14 may be deflated, and then the panels may be folded, as is indicated in Figure 6, and when this is accomplished the seats 29 may be let down to re-st on top of the panel 5, and any suitable means may be used for holding the sections in a folded position. When the float is in a folded position, it provides a very compact and convenient package to be carried around by the handle.

It is thought that the construction, utility, operation and advantages of the invention will'now be quite apparent without a more detailed description. It is desired. however, to point out that when the lever 50 is rocked, the blades 41 will tether, that i-s swing between the straightstop member 39 and the angular or Vshaped stop member 40 so as to propel the float forwardly, as will be quite apparent. The present embodiment of the invention has been disclosed in detail, merely by way of example, since in actual panels hinged to the central panel, a pair of panels hinged to two of the opposed side panels, floats carried by the other side panels and by the pair of panels, said floats being Y of the pneumatic inflatable type, a rudder hinged to one of the pair of panels, a 'seat structure on the central panel, means for mounting the seat structure so that the same may be turned, and means associated with the last mentioned means for swinging the rudder. i

2. A structure of the class described comprising a central panel, a plurality of side panels hinged to the central panel, a pair of panels hinged to two of the opposed side panels, oats carried by the other side panels and by the pair of panels, said oats being of the pneumatic inflatable type, a rudder hinged to one of the pair of panels, a seatV structure on the central panel. means for mounting the seat structure so that the same may be turned, means associated with the last mentioned means for swinging the rudder, a propeller structure rockably mount-ed on one of the side panels and having feathered blades, and means for rocking the propeller. v

3. A structure of the class described com-- prising a plurality Vof hingedly associated panels, for forming an extended or a folded float structure, collapsible pneumatic float elements associated with the panels, oneV of the panels being provided with an opening, Q

a ring rotatable on said last mentioned panel and having arms extended through the opening and supporting a bar, a pair of legs, a seat on the pair Yof legs, said legs straddling the bar vand slidable in' notches there-V of, a rudder structure, and cables extending from the rudder structure to the bar whereby the` seat may be turned to steer the rudder. Y

In testimony whereof we aliix our signatures.
